Zoogeography of Marine Mammals in Puerto Rico and the Virgin Islands
A zoo-geographical analysis of the marine mammals in the waters of Puerto Rico, US Virgin Islands and British Virgin Islands was conducted to document the presence of the different species found, and to relate their occurrences to patterns of underwater bottom topography. Past and present knowledge...
